19 Claims.

The present invention relates to improvements in typographical machines,and more particularly to-1ine casting machines of the general classdisclosed in U.S. Letters Patent No. 436,532 granted 5;, September 16,-1890 for producing type bars or slugs-from character bearing matrices,wherein assembled-.lines of matrices, each having a characterin an edgethereof, are clamped endwise between vise jaws and presented to amold-so that the character bearing portions of the matrices close thecasting cavity along the front thereof, molten-metalbeing injected intothe mold to cast the type bars or slugs -againstthe matrices and thusformprinting `characters on the front edges .e ofthe slugs.

The invention relates lmore particularly to the matrixlline'clampingjaws` of machines of this class-,and it provides novel means formounting It-hasalso been proposed to provide a rib pro- Y jectingfrom`the casting face of-a vise jaw in positionfto enter the front of themold cavity or to otherwise cooperate with the mold, as with a recess inthe face thereof, to produce slugs of lowquad height.

Molds having different height casting cavities have also been employedtoproduce slugs in the different point sizes required in printing, and tocorrespondftherewithribs of different widths are required on the visejaws and different size charactersor borders are needed. While theribsor the characters may be provided on separable or exchangeableslides in the faces of the jaws,` it has been found dicult and costly toaccurately t and securely fasten such slides into thejaw-faces and muchtime is consumed in exchanging them. Moreover, especially in the caseofv ribs intended to enter within the mold cavity or into alrecess`adjacent thereto, it has been foundfimpractical to obtain correctalinement of the lparts to permit their proper cooperation when themoldadvances in the usual manner to effect facewise and metalV tightlock up prior to casting.

f Thisdifficulty arises because of variations in dif- 1935, Serial N0.18,911

ferent machines and fromA the fact that the vise jaws, particularly ifthey are movably arranged for quaddng and centering matrixlines, musthave considerable freedom or play intheir guides A in order to avoidresistance totheir closing and opening movements.

According to the present invention, means are provided whereby avise jawwhich is inuse may be easily and quickly exchangedfor another vise jawwhenever itis necessary to substitute ajaw with a different size rib orcharacter. bearing portion on its casting face and for `adjusting thejaw to properly aline the rib or character bearing portion on` its facewith the cavity or recess in the mold. In carrying out the invention, anadjustable intermediate member is provided between the vise jaw andtheusual. jaw supporting block,,this` member being preferably carried bythe supportingblock and adapted to receive and locate the jaw thereonand to retain it yieldingly, as by a springpressed locking device whichis capable of release to instantly disconnect the jaw from its supportandpermt substitution of another jaw having a rib of different size or acasting face of different form. thereon. The present invention thus,Vovercomes the disadvantages` attendant upon the use of exchangeablecasting slides in the jaws and the adjustment `provided. for the jawenables perfect alinement of character bearing portions or low-quadcastingribs on the faces of the jaws with the mold cavity, or withcooperative recesses in the molds, to be attained when thejaws areemployed on different machines.

To these and other ends, the invention consists in certainimprovementsand combinations and` arrangements of parts all as will be hereinaftermore fully described, the features of novelty being pointed out moreparticularly in the claims at the end of this specification.

plungerd, the inner end 35er the screw'33 being conicaltoprovidea:bevelle'd surface which surrounds the depression 34 therein and issimilar tothe conical :head 25 on .the plunger 24.

The manner of applying the vise jaw to its 'adaptor member, according tothe present invention, .is shown clearly in Fig. 5, from which it willbe seen that the vise jaw is applied by engaging .the recess 23 thereinover the projection `22 .on the adaptor member and then swinging therouter end of the .jaw downwardly, whereupon downward pressure on thejaw will cause the conical or bevelled surface 35 on the screw 33 toycam .theplunger 24 inwardly by engagement with its conical head 25,.thus bringing the depression 34 in the inner end of the screw 33 intoalinement and locking engagement with the conical head 25 on theplunger. In order to insure drawing of the jaw rmly into place on theshoulder 22, a tapered pin 36 may be fixed in the upper wall of a recess31 provided in the jaw to accommodate the locking plunger 24, thistapered pin being arranged to engage against the lug 30 as the outer endof the jaw is swung into locked position, and in order to position thejaw laterally on the adaptor member, longitudinally extending shoulders38 are provided along the front and rear sides of the adaptor member,these shoulders engaging the inner side Walls of the recess 31 of thejaw as the latter moves into its locked position, thereby alining theface 39 of the adaptor member with the casting face 40 of the vise jaw.

The plunger 24 and screw 3 3 thus comprise cooperating parts toyieldingly and removably lock and retain the vise jaw rmly on theadaptor member and to permit removal of the jaw merely by forcing itsouter end upwardly to disengage the screw from vthe plunger. Theinvention thus provides means for mounting a vise jaw for pivotalmovement relative to its support and locking means releasable upon suchpivotal move` ment of the jaw to enable disconnection of the jaw fromits support for the purpose of exchanging the jaw for another jaw ofdiierent form, and an adjustable adaptor member for locating andretaining the jaw on its support, which enables the jaw to be mountedthereon in proper vertical alinement on diierent machines and in suchposition of alinement as to assure accurate engagement of a ribprojecting from the casting face of the jaw with a recess in the face ofthe mold with which it cooperates during a slug casting operation.
